Thumbelina was first climbed by Andi Turner back in 2007 and graded E7 6c. It is of that 'in-between' height, between boulder problem and route. Dropping off on to bouldering mats is okay, falling out of control from high on the route could result in injury.
Regardless of whether it was highballing or micro-routing, Katy's ascent is a fine one, and climbing these highballs is an exciting business.
"It is an awesome route, nice and crimpy. One of my favourites now!"
